Butanol-Extractable Iodine in Human and Bovine Colostrum and Milk

[摘要] High total iodine content and significant amounts of iodinated amino acids, but not of thyronines, have been reported in milk of various species. Since the human neonate requires thyroxine-like iodine compounds for central nervous system development, analyses of thyroxine-like iodine compounds such as butanol-extractable iodine of colostrum or early milk were indicated. Four samples of human milk 2-5 days post-delivery and 11 samples of bovine milk were examined for butanol-extractable iodine content. Thyroxine-like iodine compounds of colostrum or milk soon after parturition were extremely low, but total iodine values of milk supply abundant inorganic iodine for the mature neonatal thyroid.
